On social networks, many people believe that fresh longan has a cooling effect, while dried longan (longan pulp) can generate internal heat, so you should not eat too much.

Books on oriental medicine have recorded that longan has the effect of lowering blood pressure, eliminating edema, and maintaining a healthy cardiovascular system. Eating longan can help improve conditions such as rapid heartbeat, insomnia, forgetfulness, etc.

People who are irritable, easily angered, have dry mouth, sore throat and bad breath should not eat too much longan.

Longan can improve anxiety, rapid heartbeat, insomnia and forgetfulness

Lun Zhong’en, an experienced traditional Chinese medicine practitioner from Hong Kong (China), said that longan has many benefits, it is rich in nutrients such as vitamins, glucose, protein and various amino acids, as well as contains many minerals such as iron and potassium.

In particular, the high potassium content in longan has the effect of lowering blood pressure, eliminating edema, maintaining healthy cardiovascular health. Eating longan can help improve anxiety, rapid heartbeat, insomnia, forgetfulness… caused by anemia and can also promote the regeneration of hemoglobin.

In traditional Chinese medicine books, it is recorded that longan can treat the evil energy of the five internal organs, calm the mind and improve anorexia. Longan consumption can heal the soul, make people clear-minded, wise and live longer.

However, many people think that longan clears heat or generates internal heat (heat in the body) but it is not recorded. Oriental medicine practitioner Luan Trung An explains that fresh longan has just been picked so it has more water, while dried longan has less water so the sugar content is more concentrated, but the difference in their uses is not too big.

Speaking of fresh longan and dried longan, which one do you think generates more heat in the body? In fact, there is no difference between the two and fresh longan does not have the cooling effect that many people think.

The reason why the fiber and potassium content in dried longan is higher than fresh longan is because after the longan is dried, all the water is drained and the nutrients are more concentrated. Dried longan can still be added to desserts, sweet teas or cakes in the right amount to enhance the flavor.

Oriental medicine practitioner Luan Trung An said that although longan has many uses, eating too much can also cause side effects, which are not good for the body!

In addition to being picked and eaten immediately, longan can also be dried into dried longan, also known as longan pulp, which can be used to make tea or used as medicine.

Doctor Luan Trung An added that compared to fruits such as lychee or durian, longan has a mild nature and sweet taste, so women after menstruation or after giving birth can use it. In theory, longan can:

1. Support cardiovascular circulation and the spleen.

2. Calm the nerves and add vitality to the blood.

3. Improve palpitations and rapid heartbeat.

4. Prevent insomnia.

5. Reduce memory loss.

How to choose fresh and delicious longan

A longan farmer who has grown longan for more than 30 years shared that when choosing fresh longan, you should choose fruits with thin skin, shiny yellow color, thick and crispy flesh, juicy, small seeds and fragrant smell… and you should avoid choosing longan fruits that feel dry and crispy, dark skin… these are longan fruits that have been stored for a long time and are no longer fresh and delicious.

Which group of people should not eat longan?

Traditional medicine practitioner Luan Trung An said that although longan is not a hot food, people who are easily irritated, angry, have dry mouth, sore throat and bad breath should not eat too much longan.

The most obvious symptom of people who are hot-tempered and easily angered is oily and acne-prone skin. Traditional medicine often recommends that such people should eat fruits such as pears, apples and watermelon… and avoid eating lychees, durian and longan…

How many fresh and dried longan can you eat each day?

During the diagnosis and treatment process with traditional medicine, dried longan can also be added to the prescription by doctors depending on the treatment requirements of the patient.

Oriental medicine practitioner Luan Trung An said that normal people should only eat a maximum of about 30 grams of fresh longan per day, which is equivalent to about 10 longan fruits.

Meanwhile, after drying and removing the seeds, 30 grams of dried longan can be equivalent to 30 fruits, depending on whether some varieties of longan have small or large seeds. Therefore, oriental medicine practitioners recommend eating a maximum of 15 grams of dried longan, which is equivalent to 15 dried longan fruits per day.
